Automatically generate a strong and unique password from domain + your seed.
The script concatenates main domain part + your secret seed, hashes with SHA-384, then generates a 12-character password containing uppercase, lowercase, digits, and special characters using rejection sampling and Fisher-Yates shuffle. Same website + same seed = same password — no memorization or storage required.

Shift + click the 🔑 button to open the suffix input dialog. Add modifiers (like work, personal) for different accounts on the same domain, and the script will generate different passwords.
